Fed return not received yet

[April751]

My state & federal taxes were accepted on 2/14 & 2/12 respectively. I had my state refund direct deposited within a week and still haven't received my federal refund (10 weeks now). Should I be worried?

Once your return is filed, TurboTax has no control over the processing of your return or the release of your refund.

Here are a couple FAQs to track your refund:
When will I get my federal tax refund?
How do I track my state refund?
Why does Where's My Refund say "approved" but TurboTax still says "accepted"?
